Plyometrics

What are Plyometrics ?
Plyometrics (plyometric or reactive strength exercises) are a type
of exercises where you improve
the
explosive strength of a muscle without using heavy weights. Those exercises use the strength, elasticity and innervation of
the muscle and the surrounding tissue. Most plyometric exercises are designed to improve leg strength, speed
and vertical leap, but there are also plyometric upper body exercises used to improve
throws, punches and pulls. Find exercises at track and field
main.

Description: Plyometrics

Let's say you can squat 400 lbs. So you have very strong on probably really muscular legs, but that
doesn't mean that you can jump very high. Before you scream, "I knew it, big guys are slow" ,
let me tell you that in fact big muscles are fast. Most people don't know how
fast 300 lbs bodybuilders can run. After all only fast twitch muscle fiber can grow that much and therefore bodybuilders must be fast. But what you need to jump higher is not just the right muscle type. Your muscles have to react fast and what you need for this fast reaction
is an improved function of the nervous system. That's where plyometric exercises come into play. Those exercises give your muscles "reactive strength"and muscle-internal
coordination. So this is about extending the squat as fast as possible. It doesn't matter how much weight you load on your back. But of course, if you can squat your 400 lbs like if you were standing
up without resistance, your vertical will be even more impressive (see trainer advice).
